Technology

Contact Point Adjustment™

Some people like the instantaneous power of a short lever throw. Others prefer the feel of a longer throw. With Contact Point Adjust, you can pick the position you want your fingers to be in when your brakes are engaged. It’s a quick and easy way to customize the feel of your brakes without having to move the pads. It’s also a way to balance both brake levers to feel exactly the same.

Expandable Bladder

SRAM’s new brake lever design includes a reshaped bladder that helps regulate and reduce air bubbles. The bladder is specifically shaped to evacuate air from the lever and push the fluid exactly where it’s needed. The result is improved back-pressure relief, which produces dependable braking power and consistency.

Lever Pivot Bearings

Precision sealed bearings at the lever pivot enhance the clean, crisp lever actuation and consistent, light, one-finger feel.

Reach Adjust

Brake lever fit and feel is a personal thing. Riders have individual positioning preferences, as well as unique hand sizes and finger lengths. Reach Adjust makes it easy to adjust your lever for maximum one-finger control for everyone.

SwingLink™

Squeeze a new SRAM brake lever and you notice it immediately. Less deadband. More positive pad engagement. A new cam system requires less lever throw to push the pads toward the rotor. That’s great, but there’s more to perfect braking performance than just power. You need control. Many brake systems minimize deadband—but at the cost of modulation. SwingLink solves that with its special cam shape. When the pads contact the rotor, power is modulated, avoiding that “on/off” brake feel. It’s the perfect balance of power and precision.

Timing Port Closure

A hydraulic brake’s timing port is the connection between the reservoir and the master cylinder bore. When the lever is squeezed, a cup seal passes this area and closes the port, which pressurizes the system. SRAM’s new timing port closure system features durable seals and an ultra-smooth cylinder bore finish, producing dependable braking power and consistency.

SRAM Guide RSC | Editors Choice 2014 | Dirt Rag

“These are good brakes. In fact, assuming we don’t start hearing reports of Elixir-style bleeding issues, these are great brakes. Besides switching back to a tried-and-true timing-port master cylinder, a new SwingLink linkage reduces deadband, increases power, and improves feel. Top it off with a new quiet rotor design and this brake is ready to compete against the best in the business.”

SRAM Guide RSC receives high praise from BIKE Magazine’s Ryan Palmer

Notoriously known for his love of Shimano brakes, acclaimed BIKE Mag editor Ryan Palmer changed his tune saying : “I’m sick of keeping my mouth shut. The Guide RSC is the best brake I’ve ever ridden. Period.”
